BOBBiN-WlNDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,352, dated April 3, 1888.

(No model.)

To all whom it may concern.-

Be it known that I, Cnannns l3. RUMsEY, of Homer, in the county of Cortland and State of New I ork, have invented certain new and useful Improvements in Bobbin-IVinding Machines; and I do hereby declare the following to bee full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specifica tion, and to the figures and letters of reference marked thereon.

Mypreseut invention relates to machines for winding shuttle bobbins for wire -weaving looms particularly, though equally adapted for winding spools or other bobbins; and it has for its object to provide a machine by which the wire or other material can be wound directly from the reelwithout requiring the services of an operator, save for the purpose of removing the filled bobbins and replacing them by empty ones; and it has further for its object to provide simple and serviceable devices for withdrawing the wire or other material from the reel in a manner to prevent the formation of kinks and to prevent the breaking of the wire should kinks be formed therein or should the strand run beneath subsequent coils on the reel; and with these and other objects in view the invention consists in certain improved devices and combinations of parts, all of which will be described, and pointed out particularly in the claims at the end of this specification.

In the drawings, Figure 1 is a side elevation of a machine constructed in accordance with my invention. Fig. 2 is a sectional view showing themanner of mounting and disposing the withdrawing-rollers. Fig. 3 is a bottom plan view of the top of the machine, showing the arrangement of the shafts connected to the starting and stopping devices; Fig. 4, an end view of the frame in which the bobbin-rotating devices are mounted, showing the manner of inserting and removing the bobbins. Fig. 5 is a view of the lower end of the wire-reel, showing the manner of applying the brake thereto. Fig. (3 is a sectional view showing the construction of the bobbin-rotating shaft.

Similar letters of reference in the several ligures indicate the same parts.

Heretofore it has been the practice to wind the wire upon the shuttle-bobbins for looms by hand, so to speak, the bobbin being mounted upon a rotating shaft and the wire passing from a loosely-supported reel through the hand of the operator, a cloth being used for protection to the bobbin,and the operator, by a succession of short quick jerks, loosening and feeding the wire from the reel, this operation being necessary from the fact that it is put on the reel in the form of skeins or rolls as it comes from the manufacturer and forced down upon the taper thereof, so as to hold it securely, and the strand oftentimes passes under subsequent convolutions in the reel, necessitating a quick jerk to loosen it, and also to loosen any kinks that might be formed by the wire catching on strands, and in order to permit of this jerky operation some slack must be allowed. Ihe operator is usually a boy, and from carelessness or incompetency the operations necessary to cause a perfect winding are not properly accomplished, and, further, the guiding of the wire onto the bobbin being regulated by the hand which also serves to release the wire, as before stated, the wire oftentimes is not guided properly to the bobbin, but slips off and becomes wound around the bobbin-supporting shaft, necessitating a stoppage of the operation and a wasting of an amount of wire which in the aggregate (if bobbins are being wound to supply a large mill) amounts to considerable.

With the object in View of providing a machine capable of carrying out the above operations in not only a more perfect manner, but

many times as expeditiously, I have invented the herein-described device, which in practical operation I have found does the work of four operators working in the manner described above, and requiring only the attention of a single unskilled person to remove filled and apply empty bobbins.

I prefer to employ on each machine two complete bobbin-winding mechanisms, not only with the View of economizing power and for convenience of construction, but also with a view of providing two devices that can be attended to by a single-person without losing time in moving from his position at the machine, the rapidity of the operation being such that the bobbins are being removed and re- ICO placed on one device or the other almost constantly. These two winding mechanisms being precisely alike, it will be necessary to describe but one specifically.

A in the drawings represents a machineframe, consisting of the table A, with suitable supporting-legs, and having at the rear an upward extension, to which is attached a forwardlyprojecting timber, A", in which are provided bearings for various parts of the machine, to be further on described. Atthe forward end of the machine-table A is provided a casting, B, (shownin Figs. 4 and 6,) having in it the bearings fora rotating shaft,B, (shown in Fig. 6,) on the ends of which are secured the cup-shaped disks 0 0, their insides conforming to the shape of the outside of the shuttle-bobbin D, and upon this shaft, between its bearings c c, is provided abelt-pulley located within the housing or cover 0, driven by a belt, 0 from a counter-shaft, E, located at the lower portion of the frame and in turn driven from a suitably-driven belt, 13.

The insides of the disks 0 G, as stated, conform to the shape of the bobbins, and are formed with leather facings 0*,as in Fig. 6, so as to insure friction enough to rotate them when they are pressed into contact therewith. Pivoted upon the side extensions of the frame B are arms F, provided near their middles with openings for the accommodation of the extensions of the frame and perforated trans versely for the passage of the pivotal pin f, and in the upper ends of these arms are provided bearings for the studs G and the disks C the latter corresponding to the disks 0 on the driven shaft, and these studs and disks are free to rotate in said bearings, being prevented fromlongitudinal movement by collars or other suitable devices, as will be readily understood. The bobbins to be wound are placed upon the studs G against the disks 0", and the arms F turned in their pivots, so as to bring the side of the bobbins into contact with rotating disks 0, and, by the friction caused by the leather facings of the latter, rotated.

In order to cause the bobbins to be held in contact with disks by spring on a yielding pressure, and also for another purpose, to be described, Iprovide on the under side of table A horizontal shafts H H, mounted in suitable bearings, hi1, and'provided on their outer ends with handles or operating-levers H; and upon the shafts near the outer ends, beneath casting B, are rigidly secured collars I, to which are secured'one end of springs I, the other ends being connected to levers J J, sleeved loosely upon the shaft and connected by the links j with the lower end of arms F, the connection being such that when the handle H is in vertical position the upper ends of arms F will hold the bobbin against the disk 0 by springpressure alone.

At the rear end of the machine, upon the upright, is secured a bracket-arm, K, having a perforation, in which is inserted a bearingpiece, L, forming a bearing for the upper end of the spindle of a wire supporting reel, M, constructed as described and claimed in an application for patent on improvements in wire-reels, Serial No. 246,184, filed simultaneously herewith, the lower end of the spindle having a bearing in the table A. Upon this reel are placed the skeins of wire to bewound upon the bobbin, and in order to permit of the ready removal of the reel when emptyand the substitution of a full one the bearing-block L is removable and is fastened in position by a setscrew,Z,as shown. Immediately forward of the reel is a slightly-inclined roller, N, supported at opposite ends in bearings n a, secured upon long metal spring supports 0 O, fastened some distance to one side the roller, allowing the swinging of the roller in along are, and by reason of the long spring quite sensitive and yet strong. The rollers on both sides are set at the same angle preferably, to provide for a better disposition of the supporting-springs, all as shown in Fig. 2.

The rollers N N are preferably at such an angle that their ends, or at least the operating portions of them,will be always within parallel lines drawn from the sides of the reel, and their middle portions preferably cross a line from the axis of the reel, so that even when at the extremes of motion the operative portion drawing from the reel will not be outside a line from the periphery of the latter. These precise arrangements are not essential, however, though I prefer to employ them. The springs O 0 yield slightly by the pulling of the material in the direction of the reel, and their resilience brings them back to normal position again.

Immediately forward of this roller, and substantially in line with its center, is located a vertical roller, P, secured rigidly in bearings in the table and upper support, A respectively, but of course permitted to rotate freely, and the side of this roller is substantially in line with the center of the bobbin on which the wire passing from itis to be wound.

Near the lower end of the reel is located a friction drum or disk, (shown clearly in Fig. 5,) with which is adapted to co-operate at certain times a brake-shoe, Q, mounted upon an arm, Q, sleeved loosely upon the shaft Hand connected to one end of a spring, q, the other end of which is connected to a sleeve, q, secured rigidly to said shaft, the connection being such that when the shaft is turned to the left (see Fig. 5) the brake-shoe will be applied through the spring, but when turned in the opposite direction it will remove the brake, the motion of the shaft being sufficient to release the spring and take off the brake also, as will be readily understood. The object of the braking attachment is to prevent the rotation of the reel and the unwinding of the wire when the bobbin is not being rotated.

From the above description the operation of the devices will be readily apparent. wire is placed upon the reels in the skeins in which it comes from the manufacturer, the

The

taper of the reel and the slight elasticity of the wires of which it is composed holding it securely in position. Then the end of the strand is passed to the under side of the inclined roller 0, around the same, and back around the reel again above the wire thereon, this loose wire corresponding to the slack held by the operator in the hand operations. Thence it is passed to and once around the vertical roller Rand thence to the bobbin,to which it is fastened in the ordinary manner. Of course the two winding devices are the same; but to save confusion the operation of but one will be described. The operator new places the bobbin on the stud G, as-on the right in Fig. 4, and moves the lever H into upright position. This, through the medium of the spring 1, draws the arm F over and places the bobbin in contact with the disk 0, (at the same time removing the brake from the reel,) which disk, rotating rapidly, carries the bobbin with it, and this draws the wire from the reel around rollers O and P and onto the bobbin. Now, the wire, it will be noted, in passing to the under side of inclined roller 0, pulls off the reel in a straight line, and then passing over the top of the roller is directed upon the reel again, always above the wire thereon, thus allowing plenty of slack without permitting the coils to come in contact and tangle, and the jerky motion permitted by the long springbearing the roller has performs exactly the hand operation of loosening the coils of the wire and effectuallyprevents the kinking and catching of the same; and this operation or an analogous one is very essential to the perfect winding of bobbins or anything else where the material is drawn from reels on which it is loosely coiled, this applying more especially to wire. Another feature of the inclined roll is that it permits of the wire slipping up or down on it, so that the drawing in a straight line will be preserved, and this, it will be noted, renders the wire much less liable to kink than where the wire is drawn to asingle point irrespective of the point on the reel drawn from. From the upper end of the reel the wire passes to the forward roller, P, around the latter once, and then to the spool. This vertical feed-roller is also an important feature, in that the wire will not pass elsewhere than to the center of the bobbin, and then will run to the side to fill up the inequalities in winding, and the liability of running over on the shaft, as is sometimes the result of the hand operation, obviated. The passage of the wire around the reel after itpasses around the withdrawing-roller is necessary in order to give some slack to permit the springing and jerking motion ofthe latter; but it is not essential that it pass to the reel again, as other means might be employed for accomplishing this result-as, for instance, when the reel is filled clear to the top. It will be further noted that the passage ofthe wire around the reel or other support and again around the vertical guide-roller produces more friction in the direction of feed, so that the withdrawingroller will not tend to pull the wire backward to any serious extent, thereby lessening the rapidity of feed to the bobbin, but will withdraw it from the reel in the manner stated. When the attendant sees that the bobbin is full, or in another event that the reel is becoming empty, and he desires to stop the winding, he throws the lever H down to the posi tion at the right of Fig. 4, thus disengaging the bobbin from disk 0 and holding it upon stud G, at the same time turning the shaft H and applying the brake Q, to the reel, (through spring q.) stopping its further rotation and preventing the further winding of the wire. Both the holding of the bobbin in engagement and the application of the brake take place through the medium of springs, so that the former will be held yieldingly in place and the latter applied gradually withoutjerk.

Although I prefer to incline the unwindingroller, as shown, it might be more nearly vertical or quite so, and therefore the term approximately in line with theaXis of the reel is intended to mean either precisely in line or nearly so.

The advantages of the herein-described machine are so many and apparent that they will at once present themselves to those skilled in the art, as the machine is cheap, simple, and easily operated, and performs the operations required in an admirable manner.

Of course numerous modifical ions will pre sent themselves to those skilled in the art, and I do not therefore desire to be confined to pre cisely the devices herein shown and described, nor do I desire to be confined in the use of any apparatus to winding bobbins with wire; nor, as far as the operation of thewithdrawing devices and arrangement of reel and rollers are concerned, to winding bobbins at all, as the same devices might be employed for other analogous purposes.

Having thus described my invention, whatI claim as new is-- 1. In a bobbin-winding machine, the combination, with the rotating shaft having the friction-disk thereon, of the pivoted arm having the stud adapted to enter and support the bobbin and to sustain the latter when said arm is turned away from the friction-disk and the disk or collar, and arranged when turned on its pivot in one direction to bring the end of the bobbin into contact with the disk on the rotating shaft and when in the other direction to disengage the bobbin and support it, substantially as described.

2. In a bobbin-winding machine, the combination, with the rotating shaft having the friction-disk, of the pivoted arms for carrying the bobbin, having the stud and disk thereon, the lever connect-ed to said arm for turning it, and the spring interposed in said connection, substantially as described.

3. In a bobbin-winding machine, the combination, with the rotating shaft having the frictiondi'sk thereon, of the pivoted arm for carrying the bobbin, having the stud and dish, a shaft, the lever connected to the shaft, and an arm sleeved on said shaft and connected therewith by a spring and also connected to the pivoted arm carrying the bobbin, substantially as described.-

4. The combination, with the reel, of a slightly-inclined unwinding-roller,and springs in which said roller has its bearings, substantially as described.

5. The combination, with the reel, of the slight1y-inclined unwinding-roller, the springs on which it is supported, and the roller having its axis parallel with that of the reel, substantially as described.

6. The combination, with the reel carrying the material, ofa rotating shaft from which the bobbin is adapted to be rotated, devices for throwing the bobbin into rotation and disconnecting it, a brake adapted to be applied to the reel, and connections between the bobbin connecting and disconnecting devices and the brake, whereby when the bobbin is connected for rotation the brake is ofi the reel, and vice versa, as set forth.

7. The combination, with the normally rotating shaft with which the bobbin is adapted to be engaged, and devices for throwing it into and out of engagement therewith, of thereel containing the material to be wound on the bobbin, a brake adapted to be applied to the reel to stop its rotation, and connections between the bobbin engaging and disengaging devices, and the reel-brake, whereby when the bobbin is engaged with the shaft the brake will be removed, and vice versa, substantially as described.

8. Thecombination, with a rotating shaft with which the bobbin is adapted to be engaged, and devices for throwing it into and out of engagement therewith, of a reel containing the material to be wound upon the bobbin, a brake adapted to be applied thereto, and a shaft provided with a handle for operating it, to which the bobbin engaging and disengaging devices and the brake are connected on opposite sides through the medium of springs, whereby when the shaft is turned in one direction the bobbin will be held in engagement by spring-pressure and the brake released, but when in the opposite direction the brake will be applied by spring-pressure and the bobbin moved out of engagement, sub stantially as described.

9. The combination, with the rotating shaft having the disk, the pivoted arm having the stud and disk thereon, of the reel, unwinding and guide rollers, the shaft having the handle, the brake for operating on the reel connected thereto by a spring, and the spring-connection between the pivoted arm carrying the bobbin and the shaft, substantially as described.
